I. Application range of power frequency withstand test stand:
The power frequency withstand test stand is a portable experimental device. The test voltage and leakage power are all digital display and used to test motor windings and electrical components. The electrical strength and electrical leakage of electrical materials are applicable to the detection of small and medium-sized motors, high-voltage motors, and low-voltage motors.
Two. Frequency pressure test bench operating procedures:
1. First check that the power line, ground line, and the two output lines of the pressure meter (one red and one black) should be connected correctly and reliably.
2. The operator must step on the rubber insulation mat to work.
3. Wrap one red lead wire out of the two lead wires of the voltage tester and clamp the winding stator iron core lead wire three short wires (three or three tails). The other black lead wire is wrapped around the clamped winding stator core or the cleat grounded.
4. The pre-set test time is 30 seconds (continuous), and the alarm current is 100mA.
5. Press the power switch in the "ON" position (switch indicator is on).
6. When you start the test, press the start button.
7. Turn the regulator dial to raise the voltage to the test voltage of 2260V. If there is a winding stator core in the test, there is no alarm sound, indicating that the test sample being tested is qualified; if there is a winding breakdown of the winding stator core, the indicator light is bright and accompanied by an alarm sound, indicating that the test sample is unqualified. If you need to retry the test at this time, please press the reset button. Otherwise, the alarm sounds continuously, and the high pressure cannot start and cannot be detected.
Three. Power frequency voltage test bench self school:
In order to operate safely, the operator should first self-check the pressure meter before going to work every day. Do not forget.
Power frequency withstand test bench self-study program:
After the two lead wires of the pressure resistance meter are wrapped around the clamps, turn the pressure regulator, turn the dial to the zero position, start the high pressure, adjust the voltage regulator so that the voltage rises slowly to the high pressure alarm, cut off the power supply, and the self-checking is completed. After the pressure meter is calibrated, it can be checked normally.
4. The technical specifications of this procedure comply with the CB755-2000.CB14711-2006 standard.
